WHAT IT DOES

What birst_create_hierarchy does on Infor Birst MCP Server

AI agents use birst_create_hierarchy to create or update resources in Infor Birst MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Infor Birst MCP Server environment.

WHY IT NEEDS A POLICY

Why birst_create_hierarchy needs a policy

The tool creates new metadata artifacts (hierarchies) within a Birst analytics space, which is a reversible write operation. It does not execute queries, delete data, or move money. While hierarchies are foundational to analytics structure, they can be modified or removed by other tools (e.g., birst_delete_* tools), making this a standard Write-category operation rather than Destructive.

From the tool's definition Tool name contains 'create' and description states 'Create a dimensional hierarchy in a Birst space.' This is a data structure creation operation that modifies the schema/metadata of a space.
